gcloud beta compute instance-groups managed start-instances

NAME
gcloud beta compute instance-groups managed start-instances - start the stopped instances in a managed instance group
SYNOPSIS
gcloud beta compute instance-groups managed start-instances NAME --instances=INSTANCE,[INSTANCE,…] [--region=REGION     | --zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(BETA) gcloud beta compute instance-groups managed start-instances starts one or more instances from a managed instance group, thereby increasing the targetSize and reducing the targetStoppedSize of the group.

The command returns the operation status per instance, which might be FAIL, SUCCESS, or MEMBER_NOT_FOUND. MEMBER_NOT_FOUND is returned only for regional groups when the gcloud command-line tool wasn't able to resolve the zone from the instance name.

EXAMPLES
To start an instance from a managed instance group in the us-central1-a zone, run: 
gcloud beta compute instance-groups managed start-instances example-managed-instance-group --zone=us-central1-a --instances=example-instance
